It bugs me when people say “the thing is is that” (if you listen for it, you’ll start hearing it… or maybe that’s something that people only do in my area.) (“What the thing is is that…” is fine. But “the thing is is that…” bugs me.)
Also, “just because <blank> doesn’t mean <blank>.” That sentence structure invites one to take “just because <blank>” as a noun phrase which my brain really doesn’t want to do. Just doesn’t seem right. But that sentence structure is very common.
And I’m not saying there’s anything objectively wrong with either of these. Language is weird and complex and beautiful. It’s just fascinating that some commonly-used linguistic constructions just hit some people wrong sometimes.
Edit: I thought of another one. “As best as I can.” “The best I can” is fine, “as well as I can” is good, and “as best I can” is even fine. But “as best as” hurts.
On a Wednesday I would use “This Friday” or just “Friday” to describe 2 days away. Using “next” in the context you’re describing seems weird to me.
If it’s Wednesday, “Friday” or “this Friday” would describe the day in 2 days. “Next Friday” would be 9 days away. I think it’s clear and have never had an issue with people not knowing which day is being discussed. Maybe people around here are more consistent about it than other areas?
